Subscribers only
Recycled rubber materials and dense felt acoustically enhance a sculptural structure harmonizing with the forest, providing a unique venue for musical performances and community engagement.
5 key facts about this project
01
Recycled rubber surfaces enhance durability while minimizing environmental impact.
02
Dense felt insulation optimizes sound quality for performances within the forest.
03
A bent A-frame design fosters visual connection with the surrounding landscape.
04
Incorporation of traditional Latvian instruments encourages engaging musical interactions.
05
Elevated structure preserves forest floor ecology beneath the performance space.

### Project Overview
Located in a forested area of Siness, Latvia, the design emphasizes the relationship between nature and music through the integration of traditional Latvian musical instruments. The intent is to create an immersive environment that fosters interaction among performers, audiences, and the surrounding landscape. The structure serves as both a performance venue and a sculptural element, promoting community engagement and creative exploration within a natural setting.

### Spatial Organization and Acoustic Design
The layout is thoughtfully organized to encourage discovery and interaction. The overall form responds to the existing topography and tree distribution, enhancing the connection between the built environment and nature. A central gathering area facilitates performances, while a sloped courtyard optimizes acoustic projection, allowing for natural sound amplification. Instrument placement is designed to enhance the interplay between performers and audience, supported by seating configurations that augment sound projection.

### Material Selection and Sustainability
Key materials include 140x140 mm wood beams, which provide structural integrity and warmth, alongside dense felt for sound absorption. The use of recycled materials, such as old tire rubber, contributes to the durability of performance areas while demonstrating a commitment to sustainability. Thick sounding strings are utilized within the musical instruments to produce harmonic tones when engaged. Elevated above the ground, the design minimizes ecological disruption, allowing for the preservation and health of the underlying ecosystem while promoting an acoustic dialogue with the surrounding trees.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
